How do you remove glue from ceramic tile?

i would try goo gone.. it can get almost anything off!! good luck!!

ANS 2 - Depends on how much glue, and what kind . - If it's old carpet glue or similar over a large area, then Goo-Gone is NOT the answer. It would cost a fortune !. I've removed old carpet glue and old tile glues with an industrial sander (usually rentable) and very coarse paper-36 grit. It gets very dusty, so you will want a good mask and goggles if you do this.
